United States of America (USA) +001

The USA has very specific messaging restrictions and a direct connection is necessary in order to ensure message delivery to the numerous networks. ClickSend uses an extremely high-quality, direct connection in order to deliver your SMS to the USA.

You can review our best practices help article here: US Best Practices

All SMS sent to the US must originate from a pre-approved number that is associated with your account and specific use case. Replies are supported.

10DLC

With 10DLC (10-digit long codes), you can send high volumes of messages from a local number. It has been specially designed and sanctioned for business messaging. We’ll help you submit information about your brand and use case to receive a trust score which will determine how many messages you can send per day.

You can complete your 10DLC registration form here

Pre-existing long codes will be required to update to 10DLC. A 10DLC number is essentially a local 10-digit phone number that can support higher volumes of text messages.

New Update: 10 DLC in Canada. 10 DLC can be used in the US/CA. Canada customers can sign up for 10 DLC with their Canada Tax ID. For individuals resident in Canada, their authorized tax identification number is their nine-digit Canadian Social Insurance Number (SIN) issued by Service Canada.

Toll-Free Numbers

Toll-free numbers can support up to 1 message per second, we recommend keeping your transactional messages below 50,000 per day. They are well-suited for transactional messages and handset delivery reports are supported.

If you are sending low-volume marketing messages the networks are more likely to block message content such as bit.ly URL shorteners.

Toll-free numbers can be purchased directly off the dashboard.

Dedicated Short Code

Replies are supported. This option gives you the highest level of deliverability and handset delivery reports. Contact us to have this set up on your account, the setup process is 8-12 weeks.

Message length

The top 3 networks can accept multi-part (concatenated) messages (AT&T, Verizon, T-Mobile). Only Sprint and US Cellular do not accept multi-part messages. We can't guarantee the delivery of multi-part messages to the US since it's outside of our control. It's best to run your own testing for your specific use case.

Using your own mobile number

Unfortunately, you can't use your own number in the US. You can only set the (from number) as a ClickSend number you've purchased.

Alpha Tag (from name)

Unfortunately, the USA doesn't support an alpha tag e.g. (MyCompany). This is a network restriction and it outside of our control.

MMS Subject

The MMS subject line is not supported in the US and will be stripped out before sending.

Short Codes

• Short Code routes support handset delivery receipts, binary and Unicode encoding, long/concatenated messaging on most carriers. 
• There is no daily maximum of messages per day restriction on our short code routes and higher throughput is supported.
• T-Mobile and Sprint users may opt out of receiving messages from short codes to reduce the amount of marketing messages they receive. It is up to them to contact their provider to remove this.

Toll-Free

• Toll-Free numbers will not support generic URL shorteners such as bit.ly or Tiny URL link shorteners. ClickSend has a URL shortener you can use instead with SMS Campaigns.
• Do not send the same traffic over multiple Toll-Free Numbers, using multiple Toll-Free numbers is known as snowshoeing and will be blocked by the network.
